• Easy Installation & Removal – The 8mm hex socket drive allows for secure, high-torque fastening with standard tools, speeding up assembly and maintenance.
• Optimized Thread Engagement – Coarse M12x1.75mm threads with Class 5g6g fit offer quick installation and reliable holding power in a variety of materials.
• High Durability Under Stress – Made from alloy steel and hardened to Rockwell C32, the screw maintains integrity under repeated loads and vibration.
• Global Compliance & Reliability – Meets ISO 7379 standards and is RoHS 3 and REACH compliant, ensuring safe use in regulated industrial markets.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical alignment and load distribution challenges in industrial machinery, automation systems, and precision equipment. The alloy steel construction, combined with a black oxide finish, resists corrosion and wear, making it ideal for environments exposed to moisture, chemicals, or frequent movement. The 25mm shoulder length provides a stable bearing surface that prevents component shift and reduces stress on threaded sections, while the coarse thread spacing ensures faster assembly and reliable performance in high-vibration applications. Whether used in robotic arms, conveyor systems, or fixture jigs, this screw delivers consistent engineering value by minimizing downtime and enhancing operational safety.
